Be it known that l. ABRAHAM LgMonmson, a citizen or {the United statesiand a "resident of the city of Dubuque, in the county of Dubuque and State or lowa,-'l 1ave ence thereon, which form a part of this specification.

This invention relates to improvements in the guards-for wooden'poles. Heretofo're telephone, telegraph; and power line poles have had no protectionfrom prairie fires or ground, timber or grassifires, and as a result, many poles are destroyed or partially destroyed, causing wreckage of lines, great loss, inconvenience,-and oftentimes serious 'troubleto people dependingontliese services. Different sorts ofiweather protectors have been devised, butthese are'not con- 'structed for fire protection, and wouldnot prevent the POlGSfIOIH being burned adjacent the ground. In additlon, such devlces have beendifiicult to attach; in some instances impossible to" attach to standing poles as they must be inserted on one end and adjusted longitudinally of thepole.

It is an object of this invention to provide a fire, protector for the purposesspecified, in which the guard fits tightlymn the ground around the pole, completely incasin" it, and is spaced a considerable distanceii rom the pole, providing an air space of sutlicient size so that the heat of the fire cannot be transmitted therethrough to burn the pole.

It is further a very important object of this invention to provide a fire guard with a deflector for deflecting the upwardly sweeping flames outward and away from the pole, thereby permitting a relatively short guard being used, and which insures absolute protection from ground fires.

It. is further an object of this invention to provide a guard which protects the poles from direct moisture at the ground, and which thereby tends to prolong the life of the poles by checking rotting of the poles at the point and adjacent the point of entering the ground.

It is a further object of this invention to provide a fire uard which is easily and very quickly attached to any standing poles,

which is cheap to construct and practical in operation.

Other and further iniportant objects of the inventionwill be apparent frornthe dis- "closure'inthe specification and drawings.

The invention (in apreferred, form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figurel is a side elevation of a fire guard embodying the principles of thisinvention.

Fig. Qis a vertical centralsection thereof.

Fig; 3 is a top-plan view thereof.

Fig. 4 shows a modification of-a device embodying my invention.

As shown on the drawings:

'lhe'guard isiconstructed of two complelllelllittl or interchangeable sections, each comprising a seini conical sect-ion '1,'having "the lower' end o'f large diameter to provide 7 a large airspace around the pole at'the'bottom, and is tapered inwardly toward its upper end so that it contacts the pole at a suitable distance above' the ground. Said sec- 'tion is provided with a base flange 2, which.

is directed outwardly to afford a substantial support for the 7 section on *softfsoggy. ground, and which, on any kind of ground,

tends to bear firmly on thegroundfor a considerable width to preventthe possibility of the fire crawling thereunderto the pole. Preferably integral with the upper end of the firegua rd sections 1, is an outwardly directed deflector 3,"whichmay be, directed outwardly at an angle to afford the -desired angle of deflection for the fire striking thereagainst. A plurality of apertures 4, are provided at the base of the deflector just above the lineof contact of the" top of" the guard 1, to permit rain water to escape and run down the outside of the guard away from the pole. Integral with said guard sections 1, and deflector sections 3, are apertured lugs 5 and 6, adapted to receive bolts 7 by means of which said sections are rigidly secured together.

Fig. 4' shows another construction which acts substantially the same, and, as-shown, comprises semi-cylindrical sections 8, having inturned spacing flanges 9 and 10, to space the guard a suitable distance from the pole to provide a large air space to' prevent the fireirom burning the pole. Said sections are provided with a deflector 11, but this may be omitted as the spacing flanges space the shell a suflicient distance from the pole toprevent the fire lapping around the top and contacting the pole. Lug 12 and 13, are provided for rigidly securing the sec tions together as before described.

The operation of the device is seen from the foregoing description and, of course, it is understood that the device may be constructcomplemental sections from standing in the deflector bowl, and the copies of this patent may be obtained for device as a whole prevents rain water from Inoistening the pole adjacent the ground, thereby tending to check weather and moisture rot of the poles at and adjacent the point of entrance into the ground. It will be noted that the device can easily and quickly be secured in position, and that sections are interchangeable with any others, making a standardizeddevice. a I

I m. aware th'atvarious details of construction may be varied through a wide range. without departing from the principles of this inventiomand I therefore do not purpose limiting the patent granted otherwise thannecessitated by the prior art.

I claim as my invention 1. A fire guard for poles, and a deflector integral therewith.-

2. In a device of the class described, a frustum shaped guard, a base member sup porting the same, and a deflector secured to the guard.

.3. In a device of the class described, in-

terchangeable complemental sections each comprising a guard section and a deflector section, and means for rigidly securing said complemental sections together.

4-. A device of the class described embracing a conical guard section having the small end up, and an outwardly flared deflector section integral with the upper end 7 of the guard section.

deflector.

7. In a device of the class described, a conical standard, a base member supporting the same, conical deflector secured to the guard provided with escape apertures for water, and apertured lugs integral with said guard and deflector to permit the sections to be rigidly fastened together.

8. In a device of the class described, two frustum sections abutting one another, and means integral with one of said section to afford a substantial support for the device.

9. In a device of the class described embracing a guard section, and an outwardly and upwardly flared deflector section there on provided with a plurality of apertures for the escape of water therefrom.

10. In the device of the class described comprising two abutting frustums.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
